How old were you when you learned Jesus was nailed to the cross?

I don’t remember my exact age, but I remember being pretty horrified. It was too violent for my little mind, and I was not very very young. Maybe 7th grade? I heard it in passing, I was not raised Christian and my parents are not religious, so it was never discussed in my family.

I wondered when that is taught to children typically? They may know Jesus died on the cross, but when do they typically learn he was nailed? When did you learn it? Did it phase you?
